It’s an unfortunate fact of life (and business). Out of the blue you get a nasty email from someone. Sometimes it’s about an article you’ve written. Sometimes it’s accompanied by a refund request. Sometimes it doesn’t seem like it’s tied to anything at all.

Or maybe you discover someone writing malicious things about you on a blog or a forum. Or maybe some other negative things suddenly start getting tweeted or posted to Facebook about you, your products or your business.
